4930k or i7 4790

[friend_lyyy]

Hi, I recently inherited a system with an i7 4930k (previously used as a server) and was wondering if it would be a upgrade over my current i7 4790 (non K). If I do end up making the decision to switch over, I probably will overclock it (gonna try for 4.5ghz) because it came with a h100i , so please account that in when giving your advice. 

 

Thanks

What are you doing with the PC? It "might" not be as good in gaming but should be better at anything multi-threaded. The 4930K should be easy to overclock assuming the motherboard is any good, but most X79 boards are pretty good. I personally still use the X79 platform with the Xeon equivalent to the 4930k (E5-1650v2) overclocked to 4.5Ghz  and have no complaints about performance. My machine is mostly used for gaming at 1440p 144hz these days.

According to Userbenchmark, the 4930k has a higher multicore score than the 4790 (given that it has two more cores than the 4790), but has a slightly lower single core score, however since you plan to OC the 4930K, I would go for the 4930K since it has the extra two cores which can be useful depending on how you would use them, and seems to achieve better a better OC according to userbenchmark (how well a CPU can overclock varies across the same model)

The 4930K is based on an older architecture with lower IPC, but since it can OC and the 4790 is locked, that should at the very least cancel out the IPC deficit.

theres a term I haven't heard before, would you mind explaining to me what IPC is?

Instructions per clock. It's how much work a CPU core gets done per clock cycle. Combined with the clock speed that determines how much performance you get per core.

IPC stands for instructions per clock, it means that how much instructions the CPU could do per clock

the higher the IPC the better the CPU

Oh that's right! It's been so long that I had forgotten the term entirely. I'll have to study that one more

Additional notes on the platform differences. I'm sure I'm forgetting some things if anyone wants to help fill in the gaps or correct me if I'm wrong.

 

X79 (4930k)

   more PCIE lanes (40)

   Quad channel memory support (higher bandwidth)

   no iGPU (onboard graphics)

 

Z97 (4790)

   newer platform

   less PCIE lanes (16)

   Dual channel memory support (lower bandwidth)
